'The witness who saw, /He left little doubt' : a comparative consideration of expert testimony in mental disability law cases in common and civil law systems

The question of how courts assess expert evidence - especially when mental disability is an issue - raises the corollary question of whether courts adequately evaluate the content of the expert testimony or whether judicial decision making may be influenced by teleology (cherry picking evidence), pretextuality (accepting experts who distort evidence to achieve socially desirable aims), and/or sanism (allowing prejudicial and stereotyped evidence). Such threats occur despite professional standards in forensic psychology and other mental health disciplines that require ethical expert testimony. The result is expert testimony that, in many instances, is at best incompetent and at worst biased. The paper details threats to competent expert testimony in a comparative law context - in both the common law (involuntary civil commitment laws and risk assessment criminal laws) and, more briefly, civil law. We conclude that teleology, pretextuality, and sanism have an impact upon judicial decision making in both the common law and civil law. Finally, we speculate as to whether the new United Nations Convention on the Rights of Persons with Disabilities is likely to have any impact on practices in this area.

'He no doubt felt insulted': the White Australia Policy and Australia's relations with India, 1944-1964

The Government of India never publicly criticised the White Australia policy. Nonetheless it was a subject of constant reporting to New Delhi by the Indian High Commission in Canberra.  The Australian High Commission in New Delhi regularly reported criticism of the policy in the Indian press and in elite opinion.  It urged the introduction of a quota for Indian immigration to Australia, but ministers remained unwilling to modify the policy in any substantial way, in the period under study.  South Africa's apartheid policy was a far more serious problem in race relations for the Indian Government.  The existence of the White Australia policy when countries such as Canada had introduced quotas for Indian immigration, suggested an Australia mired in attitudes irrelevant to a decolonising world.  The Australian High Commissioner thought that although Nehru made no public comments on the policy, he must have felt insulted by its existence.

Popularity of reinforcement-based and belief-based learning models: an evolutionary approach

In an evolutionary model, players from a given population meet randomly in pairs each instant to play a coordination game. At each instant, the learning model used is determined via some replicator dynamics that respects payoff fitness. We allow for two such models: a belief-based best-response model that uses a costly predictor, and a costless reinforcement-based one. This generates dynamics over the choice of learning models and the consequent choices of endogenous variables. We report conditions under which the long run outcomes are efficient (or inefficient) and they support the exclusive use of either of the models (or their co-existence).

Fear of self, doubt and obsessive compulsive symptoms

BACKGROUND AND OBJECTIVES: Following observations in the literature that obsessions often contain or imply negative evaluative information about the self, Aardema et al. (2013) recently developed a measure of feared-self relevant to OCD. The current study aimed to provide further examination of the relevance of such feared self-beliefs to obsessive compulsive processes - in particular whether they partially underlie doubt in OCD-relevant situations. METHOD: Nonclinical participants (N = 463; 291 females; Mage = 25.17, SD = 7.47), were presented with three vignettes, related to washing, checking and non-OCD relevant themes, which assessed doubt through providing alternating sensory and possibility-based information. RESULTS: Higher levels of OCD symptoms and feared-self beliefs both significantly predicted both higher baseline levels of doubt and greater fluctuation in levels of doubt in both the contamination and checking scenarios, and to a much lesser extent in the control scenario. Feared-self beliefs did not predict fluctuation in doubt over-and-above OCD symptoms, consistent with a mediation model. LIMITATIONS: The main limitation was the use of a non-clinical sample, although this allowed sufficient participant numbers to test hypotheses. CONCLUSIONS: The findings provided further experimental support for reasoning processes in OCD, and suggested that feared self-beliefs may make individuals vulnerable to experiencing doubt. Additionally, these results suggested that individuals with high OCD symptoms and those with high feared self-beliefs are unable to recognise the improbable nature of possibility-based statements. Implications for treatment and theory are discussed.

The role of fear of self and responsibility in obsessional doubt processes: a bayesian hierarchical model

The literature concerning obsessive-compulsive disorder (OCD) indicates that obsessions frequently imply negative evaluative beliefs regarding the self. The construct of the feared self has been used to describe the set of harmful attributes an individual worries they may possess. This study aimed to partially replicate previous research that demonstrated a relationship between feared-self beliefs and obsessional doubt in OCD-relevant contexts. The relationship between perceptions of personal responsibility and associated levels of doubt was also examined. Nonclinical participants (N = 221; 155 female; Mage = 26.4, SD = 9.2) were presented with vignettes related to checking and non OCD-relevant themes, which quantified doubt through the presentation of alternating reality-based (i.e., sensory) and possibility-based information. Of the total sample, 112 participants were randomly allocated to a personally relevant condition (in which the action implied in the vignettes was completed by the reader), and 109 were allocated to a second, other-relevant, condition (in which the action implied in the vignettes was completed by a proximal other). The results provided support for reasoning processes implicated in OCD, suggesting that feared-self beliefs may partially contribute to heightened levels of doubt in response to possibility vs. reality-based information in OCD-relevant contexts. Personal relevance contributed to greater baseline levels of doubt, but not to greater responses to the reality- and possibility-based statements accompanying the OCD-relevant vignette. Implications for theory and future research are discussed.

Better the devil you know than a world you don't? Intolerance of uncertainty and worldview explanations for belief in conspiracy theories

Conspiracy Theory (CT) endorsers believe in an omnipresent, malevolent, and highly coordinated group that wields secret influence for personal gain, and credit this group with the responsibility for many noteworthy events. Two explanations for the emergence of CTs are that they result from social marginalisation and a lack of agency, or that they are due to a need-to-explain-the-unexplained. Furthermore, representativeness heuristics may form reasoning biases that make such beliefs more likely. Two related studies (N = 107; N = 120) examined the relationships between these social marginalisation, intolerance of uncertainty, heuristics and CT belief using a correlational design. Overall, intolerance of uncertainty did not link strongly to CT belief, but worldview variables did - particularly a sense of the world as (socially) threatening, non-random, and with no fixed morality. The use of both representative heuristics that were examined was heightened in those participants more likely to endorse CTs. These factors seem to contribute to the likelihood of whether the individual will endorse CTs generally, relating similarly to common CTs, CTs generally historically accepted as "true", and to the endorsement of fictional CTs that the individual would find novel. Implications are discussed.

Factors associated with breast and cervical cancer screening behaviours

To investigate the factors associated with the use of screening mammography for breast cancer and cervical smear tests for cervical cancer, a theoretical framework was used comprising elements from the Health Belief Model, the Theory of Reasoned Action, and illness representations from the self-regulatory model. Items reflecting older women’s illness representations about cancer and cancer screening were derived from an earlier qualitative study. Using a highly structured interview schedule, telephone interviews were conducted with 1,200 women aged 50-70 years. There were considerable similarities between the factors associated with both mammography and cervical smear test behaviours. The factors associated with screening mammography behaviour were: perceived barriers, perceived benefits, social influence, the illness representations, and marital status. The factors associated with cervical smear test behaviour were: perceived barriers, perceived benefits, emotions as a cause of cancer, feeling frightened of cancer, the illness representations, having a usual general practitioner, and being younger.

Relationships between identity and self-representations during adolescence

By drawing from literature on identity development as well as on self-discrepancy, the present study aimed to investigate variations in the magnitude of self-belief discrepancies among adolescents with different levels of identity development. The respondents consisted of 336 male and female adolescents, from 5 private secondary schools, ranging in age from 14 to 18 years (M = 15.98, SD = 0.89). Four levels of identity status (Achieved, Moratorium, Foreclosed, and Diffused identity status) were used as the method of identity classification in this study. Four types of self-discrepancies (Actual/Ideal (own), Actual/Ideal (other), Actual/Ought (own), and Actual/Ought (other) self-discrepancy) were also obtained. Multivariate analyses of variance showed that respondents with different identity statuses significantly varied on the magnitude of self-discrepancy experienced. The Foreclosed and Achieved statuses were found to have lower levels of self-belief discrepancy than the Moratorium and Diffused statuses. However, most of the significant differences among the statuses were for the Actual/Ideal (own) and Actual/Ideal (other) self-discrepancies. These results indicate that identity development is related to the magnitude of self-belief discrepancy. However, further research with more developed instruments is needed to explore this relationship more fully.

Blaming the target of sexual harrassment: impact of gender role, sexist attitudes and work role.

This study was conducted to examine factors associated with blaming the target of sexual harassment. Participants' experiences of sexual harassment, sexist attitudes, gender, gender role identity, age, worker or student status, and belief in a just world were included as independent variables. Level of blame was evaluated using a series of 12 vignettes that manipulated the gender of the target and harasser as well as the seriousness of the harassing behavior. The sample comprised 30 female and 32 male workers from two workplaces, whose ages ranged from 18 to 65 (M = 35) years, and 102 female and 18 male university students whose ages ranged from 17 to 40 (M = 21) years. Approximately 70% of the sample were from Anglo Australian background, and 30% from European, Middle Eastern or Asian background. Females experienced more sexual harassment than males did, although the male rate was higher than expected. Although the majority of subjects attributed little blame to the target, males blamed the target of sexual harassment more than females did, and workers blamed the target of harassment more than university students did. Worker status, sexist attitudes, and gender significantly predicted blame for the total sample. Gender-typing increased the blame of the target by males but not by females. Attribution of blame was significantly influenced by worker versus student status, which supports the social psychological perspective that gender-related behavior is context dependent. The findings from this study suggest that organisational culture and environment influence respondents' attitudes to sexually harassing behavior.

Physical disability and sexual esteem

The current study investigated the impact of physical disability on sexual feelings, sexual experiences, and sexual esteem. Thirty-five respondents (18 males and 17 females), with physical disabilities between 19 to 60 years (SD = 10, mean = 38) participated in focus groups where they discussed how their physical disability impacted on their sexuality. They also responded to a series of questions that were designed to examine disability-specific issues in sexual esteem using a four-point Likert-type scale. The data demonstrated that the participants struggled with many social and sexual barriers that were associated with having a physical impairment. This appeared to lead to increased feelings of negativity in many participants, including a belief that they were less sexually desirable than an able-bodied person and that having a disability seriously limited their sexual expression. The implications of these findings for practitioners and suggestions for future research are discussed.

Limitations to free association and interpretation

A core challenge that emerged from the historically based critique of Freud's work that constitutes Freud Evaluated: The Completed Arc (Macmillan, 1991, 1997) was to Freud's claim that the basic rule of psychoanalysis for inquiring into the causes of symptoms was unaffected by his “suggestions.” That is, in demanding that the patient tell the analyst whatever came to mind with complete candor, the patient would not be led astray by the analyst's ideas about the possible causes of the symptoms. In this article, the assumptions underlying Freud's belief in the validity of the method of free association are made explicit and criticized. The basic indetermination inherent in interpreting material apparently recovered by the method is also made explicit. Some of the consequences of the method for psychoanalytic developmental theories and for deciding between the variant schools of psychoanalysis are set out.

A model for compressing probabilities in belief networks

Probabilistic reasoning with belief (Bayesian) networks is based on conditional probability matrices. Thus it suffers from NP-hard implementations. In particular, the amount of probabilistic information necessary for the computations is often overwhelming. So, compressing the conditional probability table is one of the most important issues faced by the probabilistic reasoning community. Santos suggested an approach (called linear potential functions) for compressing the information from a combinatorial amount to roughly linear in the number of random variable assignments. However, much of the information in Bayesian networks, in which there are no linear potential functions, would be fitted by polynomial approximating functions rather than by reluctantly linear functions. For this reason, we construct a polynomial method to compress the conditional probability table in this paper. We evaluated the proposed technique, and our experimental results demonstrate that the approach is efficient and promising.
